I have a 78 standard (i think that's what its called, please confirm/deny) and an 82 custom, I want to fix the 78 (see attached pics). I noticed that the 82 has the twin pot brake caliper and the 78 is a single. I'd like to swap the 82 in but noticed several issues:
1) Fork leg caliper mounting brake hole spacing is different
2) Fork diameter is different
3) Fork leg length is different
4) Fork geometry is different - one is a leading axle and the other isn't
5) One has air adjustable pre-load and one doesn't
If i could just bolt on the 82 caliper to the 78 i would but the bracket spacing is different, is there a way to do that or am i missing something?
So, i was pondering the idea of swapping the whole front end out but don't know if the steering stem is interchangeable between the two and if the steering geometry would be all out of wack even if the stem could be swapped? I am hoping someone has been down this road before and has an answer. If i have to go with the stock single pot so be it if the swap doesn't make sense. Any comments/suggestions welcome.
Thanks,
Doug
